I am looking to create a fitment guide for our magnums. I need your guys help. Please list the tire size and rim size of combinations that will fit.

I.E. 275/45/20 on a 20" x 9" rim.

UPDATE:

Here is some info I have found.

The LX platform is designed to accommodate up to a 275mm width up front and a range offset from 12.5mm to 24mm. You want to stay between 28.6" and 29.3" in tire diameter, optimally. You can go as small as 28.3" in tire diameter to keep everything calibrated correctly on our cars, but no smaller.

Magnum Bolt/Lug pattern = 5X115

20"x9.5" - 12mm to 20mm offset

18" tire recommendations

255/55/18

20" tire recommendations

255/45/20
245/40/20 - smaller OD from stock and will leave a bigger gap
275/40/20 - comes close to fender, but shouldn't cause any clearance problems

22" tire recommendations

Front
255/30/22
265/30/22
265/35/22

Rear
255/30/22
295/30/22
265/30/22
265/35/22


Here is a good site with info and comparisons on tire sizes/offsett and backspacing - Wheel / tire size calculator / comparer - BIGCUSTOMWHEELS

Please double check with your tire shop. I don't want to be held responsible for you purchasing a set of wheels that don't fit. If see anything thing that needs corrected, please let me know.

I am going to attempt a 265/30zr22 on my magnum. The wheels ar 22" TIS 10s. 18mm offset, and backside spacing of 6/153. Tire rack says it works, we will see. If it doesnt I will be very very upset.

Thanks for the link to big custom wheels, i'm in the process of upgrading my RT wheels to a set of SRT 8 wheels and i thought i would have a big gap due to the low profile tires but it turns out that i will be getting just a bit more tire. Rear 255/45/20 an front will be 245/45/20 as compared to the 225/60/18 that comes stock.
Thanks,
Chris

I am interested in the stock 20's. Where are you located, and what kind of price are you looking for?

22"x9.5" with a +13mm offset. 265/35/22 Nitto's. The offset is a bit extreme, since I can see the edge of the tire just a bit outside of the fender, which is gonna make it impossible to go very low, with springs or bags I'm thinking

I went with 245/45/20 on a 20x8.5 wheel.

I had 245/40/20 and the sidewall was just too small and left too large a gap between the tire and the wheel well. But I did get close to a full MPG better with the smaller overall diameter...not to mention my old wheels were about 3 pounds lighter a corner).

sounds like a good plan, I think I got the mrs talked into going with springs till we can afford bags...

Nope. RWD aftermarket you typically run et (offset)+15 to +18.
AWD's are an et (offset)+50 to +55 stock.
You can still run up to a 24" wheel on AWD's but the choices get dramatically slimmer.
Problem I ran across was that LX cars are pretty much all (besides the Rolls Royce Phantom) that can fit that big of an overall wheel diameter with little to no modification. Some TRUCKS can't even hold 24's (Range Rover can't). Add that to the fact that most LX owners have RWD and you'll see why there are alot of wheels for the RWD but not the AWD.

On The 300 we have Akuza Rewind whls @20"x9 w/+14 offset with Toyo Proxes s/t> @P255/45R20

On> The Magnum we have Diablo Instinct whls @20"x8 with BFGoodrich KDW @P245/40ZR20


The tire on the 300 fills the gap much better and the ride is much smoother.

Magnum tire is firmer but slightly ruffer but not much.

22X9 up front with 265/35/22s, 22X10 out back with 305/30/22s. It's a bit aggressive.. in fact, the rears look angry and stick out a little more than I was expecting, but there is no rubbing at all. The 305s rub on the Charger / 300, but not the Mag!
